ed certain new and useful Improvements in Journal-Boxes, of which thefollowingis a specification.

This invention pertains to improvements in journal-boxes, and will bereadily understood from the following description, taken in connectionwith the accompanying drawing, in

which- Figure 1 is an end elevation of a journalbox, illustrating anadaptation of my invention to a bearing in pedestal form, a portionappearing in vertical section; Fig. 2, a side elevation of the same;Fig. 3, a vertical transverse section; Fig. 4, a vertical longitudinalsection, and Fig. 5 a perspective View of the bushing with the upperhalf appearing in vertical transverse section.

In the drawings, 1 indicates a base-piece having the form of anopen-topped trough; 2, a pedestal supporting the same and constituting,so far as invention is concerned, a mere exemplification of means forrigidly supporting the base-piece 1; 3, a cap, bolted to and closing thetop of the base-piece; 4, a bed-box fitting nicely within the trough ofthe base-piece and adapted for vertical movement therein, this bed-boxbeing in the form of a hollow shell adapted to form an oil-cellar; 5,transverse partitions in the lower portion of the bed-box dividing theside walls thereof and dividing the oil-cellar of the bedbox intoseveral compartments, connected, however, by ports through the lowerportions of these partitions, so that the oil has free access from onecompartment to another; 6, a cylindrical bore cutting half up into thecap 3 and half down into the end walls and partitions of bed-box 4, thisbore being somewhat larger than the shaft which the bearing is to serve;7, counterbores at the ends of the bore 6, partly-in the cap and partlyin the bed-box 4; 8, the bushing, considered as a whole, the same havinga cylindrical bore to fit the intended shaft and having an exterior tofit the bore 6 and having head-flanges to fit counterbores 7 the bushingbeing therefore of general spool form and being also split in a centralhorizontal plane; 9, the upper half of the bushing, being that portionfitting within the cap 3, this half of' the bushing being doweled forthe cap, so as to prevent rotation of the bushing; 10, the lower half ofthe bushing, being that portion fitting in the bore of the bed-box 4;11, the shaft-journal, fitting the bore of the bushing; 12, acircumferential groove cutting entirely through the bushing, preferablyat its center of length, as shown, this groove, as far as thusconsidered, cutting the entire bushing transversely in two; 18, a bridgeacross the lower portion of the groove, formed by interrupting thegroove at the lower portion of the bushing, this bridge serving to unifythe two end portions of the lower half of the bushing; 14, segments ofbands projecting across over the groove 12 on the upper half of thebushing, a gap being left between the inner upper ends of the twosegments, the segments 14 and the bridge 13 being formed integrally withtheir appropriate bushing halves, so that they are properlystrengthened, notwithstanding the presence of the groove 12, the bore ofthe cap 3 having a semicircular recess to make room for the segments 14;15, an endless chain hanging upon the shaft-journal at groove 12 andhanging down within the cavity of the bed-box 4.; 16, a wedge disposedupon the floor of base piece 1 and extending substantially the length ofbed-box4 and having its'upper surface transversely inclined and engaginga correspondingly-inclined lower surface of the bed-box 4, whereby thetransverse shifting of the wedge will effect the vertical adjustment ofthe bed-box and the bush- I ing half carried by it; 17, adjusting-screwsfor transversely shifting the wedge, the same preferably consisting oftwo set-screws threaded through the side wall of the base-piece andimpinging against the wedge and serving to adjust it inwardly, and astud secured in the wedge and projecting through the side wall of thebase-piece and provided with, an exterior nut to serve in adjusting thewedge outwardly; 18, a large oil-hole in the cap 3 over the gap betweenthe contiguous ends of the segments 14; 19, plates secured against theends of base-piece 1 and closing the ends of the trough therein, theseplates serving in the illustration to merely exemplify end closures forthe base-piece, which end closures while preferable are not essential;20, annular recesses at the ends of the bore of the bushing; and 21,ports leading from the bases of these recesses diagonally downward andinward through the bushing and through the end walls of bed box 4 intothe oil-cavity in the bed-box.

Oil-supply through oil-hole 18 passes downward through groove 12 intothe oil-cellar in the bed-box. In the operation of the journal the chaincarries the oil upward to the journal, whence it becomes distributedover the bearing-surfaces, such surplus as works outwardly returning tothe oil-cellar by way of the recesses 20 and ports 21. By shifting thewedge the lower half of the hearing may be adjusted upwardly to thejournal, and in case the cap 3 is originally fitted down solid to thebase-piece the contacting surfaces between cap andbase-piece may beeased away in case it is desired to shift the bearing downwardly. It isto be observed that notwithstanding the rather complicated form of thebushing-and the bold grooving of it to make room for the chain it hasample strength and is susceptible of being fitted by simple lathework,and it is also to be observed that the boring of the cap and bed-box toreceive the bushing is independent of the base-piece and also that thebase-piece has no oil-holding function.

While I have illustrated my improved journal-box by an adaptation to apedestal-bearing, it is manifest that it will lend itself to any of theusual systems in lieu of a pedestal for supporting a bearing.

I claim as my invention- 1. In a journal-box, the combination,substantially as set forth, of a troughlike basepiece, a wedge disposeduponthe floor of the trough of the base-piece, means for shifting thewedge, a hollow bed-box fitting within the trough and resting upon thewedge, a boxcap secured to the top of the base-piece, the cap portion ofthe bearing being provided with a semicircular groove open to thebearing-surface, and the bed portion of the bearing being provided withslots open to said groove and to the cavity of the bed-box, and anendless chain disposed within said groove and hanging down through saidslots into the cavity of the bed-box. v

2. In a journal-box, the combination, substantially as set forth, of atrough-like basepiece, a wedge disposed upon the floor of the trough ofthe base-piece, means for shifting the wedge, a hollow bed-box fittingwithin the trough and resting upon the wedge, a boxcap secured to thetop of the base-piece, bushing halves fitting the bores of the box-capand bed-box, the upper bushing half being provided with asemicylindrical groove open to the bearing, and the lower bushing halfhaving slots communicating with said groove and also open to the cavityof the bed-box, and an endless chain disposed within said groove andhanging down through said slots into the cavity of the bed-box.

3. In a journal-box, the combination, substantiall y as set forth, of atrough-like basepiece, a wedge disposed upon the floor of the trough ofthe base-piece, means for shifting the wedge, a hollow bed-box fittingwithin the trough and resting upon the wedge, a boxcap secured to thetop of the base-piece, a half-bushing fitting the bore of the cap andhaving a semicylindrical groove open to its bearing and rooted bysegments separated from each other at a point over the axis of thejournal, a bushing half fitting the bore of v the bed-box and havingslots communicating with said groove and also with the cavity of thebed-box, and an endless chain disposed in said groove and hanging downthrough said slots into the cavity of the bed-box.

4. In a journal-box, the combination, substantially as set forth, of atrough-like basepiece, a wedge disposed upon the floor of the trough ofthe base-piece, means for shifting the wedge, a hollow bed-box fittingwithin the trough and resting upon the wedge, a boxcap secured to thetop of the base-piece, said bed-box and boxcap being provided at eachend with annular recesses open to their bores and having communicationwith the cavity of the bed-box by means of ports in the bed-box,

, the box-cap being also provided with a semicircumferential groove opento the bearing, and a bed-box being provided with slots com inunicatingwith said groove and with the cavity of the bed-box, and an endlesschain disposed in said groove and hanging through said slots down intothe hollow of the bed-box;
